Clay refractory bricks are widely used in many high-temperature industrial fields because of their excellent high temperature resistance, corrosion resistance, wear resistance and thermal shock resistance. The following are the main application industries and specific uses of clay refractory bricks:

I. Steel industry

Iron and steel industry is one of the main application fields of clay refractory bricks, covering almost every link from iron ore smelting to finished steel production.

Blast furnace: The bottom, hearth, shaft and other parts of blast furnace need to withstand the erosion of high-temperature molten iron and slag, and clay refractory bricks can provide good protection. High alumina clay bricks are often used in key parts of blast furnace, such as bottom and hearth, while ordinary clay bricks are used in furnace shaft and other parts.

Hot-blast stove: Hot-blast stove is used to preheat air to high temperature and then send it to blast furnace. Clay refractory bricks are used in the vault, checker bricks and other parts of hot-blast stove, which can withstand frequent temperature changes and high-temperature airflow erosion.

Ladle and ladle: containers for holding high-temperature molten steel and molten iron. Clay refractory bricks can withstand the erosion and thermal shock of high-temperature liquid.

Heating furnace: a heating furnace used to heat the billet to the rolling temperature. Clay refractory bricks are used for furnace lining, which can withstand high temperature and wear of materials in the furnace.

Converter and electric furnace: converter and electric furnace used for steelmaking, clay refractory brick used for furnace lining, can resist the corrosion of high-temperature molten steel and slag.

II. Building materials industry

Building materials industry is another important application field of clay refractory bricks, especially in the production of cement and glass.

Cement rotary kiln: Cement rotary kiln is the core equipment of cement production. Clay refractory bricks are used as the lining of rotary kiln, which can withstand chemical erosion and mechanical wear during high temperature sintering of cement clinker.

Preheaters and calciners: Preheaters and calciners used in cement production. Clay refractory bricks can withstand the erosion and chemical erosion of high-temperature airflow.

Glass melting furnace: Glass melting furnace is used to melt glass raw materials, and clay refractory bricks are used in the breast wall, crown and other parts of the furnace, which can withstand the high temperature erosion of glass liquid and the erosion of airflow.

III. Energy industry

Many equipments in the energy industry need refractory materials to protect them, and clay refractory bricks are also widely used in these fields.

Coke oven: a coke oven used for coking, and clay refractory bricks are used for lining, which can withstand the corrosion and chemical reaction of high-temperature coke.

Boilers: including coal-fired boilers, oil-fired boilers and gas-fired boilers. Clay refractory bricks are used for furnace lining and can withstand the erosion of high-temperature flames and flue gas.

Garbage incinerator: a boiler for burning garbage. Clay refractory bricks can resist chemical erosion and ash abrasion caused by high-temperature garbage combustion.

Circulating fluidized bed boiler: This kind of boiler needs refractory materials to withstand the wear and chemical erosion of high-temperature particles, and clay refractory bricks are an ideal choice.

IV. Chemical industry

Many high-temperature reaction furnaces and equipment in chemical industry also need refractory materials to protect them.

Petrochemical cracking furnace: a high-temperature furnace used for petroleum cracking. Clay refractory bricks can withstand high temperature and chemical reactions.

Sulfuric acid furnace: a high-temperature furnace used to produce sulfuric acid. Clay refractory bricks can resist the corrosion of sulfuric acid vapor.

In other chemical furnaces, such as oxidation furnaces and reduction furnaces, clay refractory bricks can withstand both high temperature and chemical reactions.

V. Ceramic and refractory industries

In the production of ceramics and refractories, refractories are also needed to protect the production equipment.

Ceramic kiln: a kiln used for firing ceramic products. Clay refractory bricks are used for kiln lining, which can withstand chemical erosion and mechanical wear during high-temperature firing.

Refractory production kiln: a kiln used for firing other refractories, and clay refractory bricks are used for kiln lining, which can withstand chemical erosion and mechanical wear during high temperature firing.

VI. Civil field

Clay refractory bricks also have certain applications in civil fields.

Fireplace: Fireplace used for home heating. Clay refractory bricks can withstand the erosion of high-temperature flames and have good thermal insulation performance.

Pizza oven and Outdoor Oven: Ovens used for cooking pizza and other foods. Clay refractory bricks can withstand the erosion of high-temperature flames and have good thermal insulation performance.

VII. Other areas

Non-ferrous metal smelting: a high-temperature furnace for smelting non-ferrous metals such as copper, aluminum, lead and zinc. Clay refractory bricks can resist the erosion of high-temperature molten metal and slag.

Lime kiln: a kiln used to produce lime. Clay refractory bricks can withstand high temperature and chemical reactions.

Casting furnace: a high-temperature furnace for casting metal. Clay refractory bricks can withstand the erosion and thermal shock of high-temperature molten metal.

VIII. Summary

Clay refractory bricks are widely used in steel, building materials, energy, chemical industry, ceramics, civil and other industries because of their excellent high temperature resistance, corrosion resistance, wear resistance and thermal shock resistance. These industries have a high demand for the protection of high-temperature equipment, and clay refractory bricks can effectively prolong the service life of equipment, improve production efficiency and reduce maintenance costs.
